AssertionError in 3.15: "either include a queryset attribute, or override the get_queryset() method"

[kevinrenskers]

I have a view where users can fetch and patch their own account settings:

class AccountSettingsView(RetrieveUpdateAPIView):
    serializer_class = AccountSettingsSerializer
    permission_classes = [permissions.IsAuthenticated]

    def get_object(self):
        return AccountSettings.objects.get(user=self.request.user)

Works fine with DRF 3.14 but with 3.15 this now fails: AssertionError: 'AccountSettingsView' should either include a querysetattribute, or override theget_queryset() method.

Why is this necessary now? I don't need a whole queryset if only one single object is supported, which it gets in get_object, I would think? I haven't seen breaking changes about this in the changelog?
